Transcript of Goats Agricultural Production and Breeds
- PRODUCTION –
Care, Feeding, Breeding, Economics
one of the smallest domesticated ruminants
has served mankind earlier and longer than cattle and sheep.
is managed for the production of milk, meat and wool
460 million goats worldwide produce more than 4.5 million tons of milk and 1.2 million tons of meat Also mohair, cashmere, leather and dung;
More people consume milk and milk products from goats worldwide than from any other animal.
In the United States there are between 2 and 4 million head of goats Texas leads in Angora, meat and bush goats; California leads in dairy goats.
Breeds of goats vary from as little as 20 lb mature female bodyweight and 18 inches female withers for dwarf goats
Meat and milk production up to 250 lb and 42 inches withers height for Indian Jamnapari, Swiss Saanen, Alpine and AngloNubian
Some Jamnapari males may be as tall as 50 inches at withers
Angora goats weigh between 70 to 110 lb for mature females and are approximately 25 inches tall.
Birthweights Female singles are between 3 and 9 lb
Twins often a pound lighter Males 1/2 lb heavier.
Twinning is normal in goats witha high percentage of triplets Some breeds have an average annual litter size above 2 per doe or more than 200% reproduction rate.
Goat Terms:
Female – Doe
Intact Male – Buck
Castrated Male – Wether
Young – Buck or Doe Kids or Doelings
goats may have horns of the scimitar or corkscrew types
many are dehorned in early age with a heated iron, caustic or later on with a rubber band or surgical saw
Goats may also be genetically hornless
Goats can be short haired, long haired, have curled hair
They are silky or coarse wooled
They may have wattles on the neck and beards.
Swiss and other European breeds have erect ears
Indian and Nubian have pendulous, drooping, large ears
American LaMancha breed has no external ear
Goats come in almost any color, solid black, white, red, brown, spotted, two and three colored, blended shades, distinct facial stripes, black and white saddles, depending on breeds.
The digestive tract of the goat after nursing has the typical four stomach compartments of ruminants
the rumen (paunch) (4-6 gallon) #2
the reticulum (honeycomb) (1-2 liters) #3
the omasum (maniply) (1 liter) #4
the abomasum (true stomach) (3.5 liters) #5
The intestinal canal is about 100 feet long (11 liters), or 25 times the length of a goat. #6
DiseasesGoats are not too different from cattle and sheep in the same regions
Goats have more internal parasites than dairy cows
They have less tuberculosis, milk fever, post partum ketosis and brucellosis than dairy cows
Their milk tends to be of lower bacteria counts than cow milk
They have more prepartum pregnancy toxemia than dairy cows
Goats may have laminitis, infectious arthritis, Johne's disease, listeriosis, pneumonia, coccidiosis, scours, scabies, pediculosis, liver fluke disease and mastitis.
goats breed normally from August through February
Twins are common, triplets are not rare
Goats are in puberty at 1/2 year of age and can be bred if of sufficient size.
Does come into estrus in 21 day cycles normally, lasting approximately 1 to 2 days.
Length of pregnancy is 150 days
Two litters per year is possible
Saanen - from Switzerland
Totally white, with or without horns.
Mostly short haired.
Have been exported around the world as leading milk producers.
An Australian Saanen doe holds the world record milk production of 7,714 lbs in 365 days.
Saanen were originally bred for odor free milk.
Toggenburg
From Switzerland
Brown with white facial, ear and leg stripes Straight nosed, horned or hornless, Mostly shorthaired, erect eared goat, Reliable milk producers summer and winterBred pure for over 300 years
LaManchaDeveloped in California from Spanish Murciana origin and Swiss and Nubian crossings.
They have straight noses, short hair, hornless or horns, No external ear due to a dominant gene.
Known for excellent adaptability and good winter production.
Produce fleshier kids than the Swiss, but are not milking as much.
(Anglo)-Nubian Developed in England from native goats and crossed with Indian and Nubian
Have heavy arched ''Roman'' noses Long, drooping, pendulous earsSpiral horns and are shorthaired.
Are leggy and as tall as Saanen, but produce less milk, though higher milk fat levels Are more fleshy. Less tolerant of cold but do well in hot climates.
They ''talk'' a lot, and are in numbers the most popular breed in USA and Canada. Have a tendency for triplets and quadruplets. Are horned or hornless and have many colors that may be ''Appaloosa''-like spotted.
AngoraOriginated in the Near East.
Long upper coat (mohair) is the valuable product in the Angora in contrast to the Cashmere, where the fine underwool is the valuable product.
Head has a straight or concave nose, thin, not very long; pendulous ears and twisted horns, in both sexes.
Small breed, usually white. The haircoat is long with undulating locks and ringlets of fine, silky hair. The top quality fleece of purebreds may be 1-2 lbs, but slightly more in males and wethers.
They are bearded. Spring moult is natural and shearing occurs just before. Not very prolific and twinning is less frequent than in other breeds
Pygmy
From West and Central Africa
Are dwarf, short legged goats
Growth rate and milk production are lower than standard size
Twinning is frequent
They breed all year
Bred mostly as pet or for genetic purposes
Housing
Standard goats require large pasture
Pygmy Goats much less – some kept in homes
Fencing is essential – goats get out of fence not made especially for them
A shed to get out of weather is helpful
House Bucks and Does separately
Feeding
Goats require pasture and foraging
Also feed good commercial goat food
(dry rolled ration – Corn, Oats, Barley)
Maintain constant, clean water
Do Not overfeed rations – they make up what they need in grass and bushes
Alfalfa Hay is alternative when pasture is small
Medical Care
Require tetanus and possibly BoSe (selenium supplement)
Regular trimming of hooves – garden or sheep trimmers
Possible worming needed
Lice shampoo
Grooming – especially for Pygmy or Angora
Normal temperature is 102.5
Popularity
Goats are most popular 4-H or FFA Project
Easy to raise
Fun to own
Adapt well to living with people
Social animal – have
more than one
